After the pipe is cleaned, the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately, so that dust and dirt will not pollute the capillary gap.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.Oldenburg,To prevent the copper pipe surface, the humidity of the packaging materials should be well controlled and the moisture content of all wood and paper packaging materials should be strictly controlled below %. Each plate of material is tightly packed with PE film to avoid the copper pipe absorbing moisture from the outside.Because of the characteristics of copper itself, it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it, but if it is placed for a long time, the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.Rio de Janeiro,Advantages of red copper tube Durability: copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance and can be used in different environments for a long time.Hygiene and health: various modifiers, additives, additives and other chemical components of plastic pipes in copper pipes.It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, they must be isolated.

The production method of soft copper tube is basically the same as that of hard copper tube that is, the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However,OldenburgTinned copper bar, after annealing, the copper tubes will become soft, which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.If the copper tube is blocked during use, it is also very important to dredge it in time.antages: low production cost and high production efficiency.Job description,Oldenburg304 stainless steel plate,OldenburgAluminum rod, more and more steel plants have stopped production since October, and the production limit in Wu an and Tangshan heating seasons has been advanced. In addition, the formal implementation of production limit in & quot; +& quot; urban heating seasons after November by steel enterprises, the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high, and the willingness to further replenish the inventory is not strong. In terms of supply, the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection, the quantity of * * * is relatively limited. In general, the short-term iron ore market may lack upward momentum.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.The blowpipe shall be perpendicular to the lead pipe during welding, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.

For small diameter pipes, when using filler metal, the length of filler metal is allowed to be equal to the diameter of the pipe, which is enough to fill the weld crater. One of the five major application fields of red coppr plate T, red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries, motors and transformers, switches and printed circuit boards; In the manufacture of machinery and transport vehicles, it is used to manufacture industrial valves and accessories, instruments, sliding bearings, molds heat exchangers, pumps, etc.production,When placing, they should be stored separately according to the different components, and should not be mixed together. The copper surface may have electrolytes, so it will react, especially with other materials such as rubber, which has a large impact.For the deposited copper tubes, do not open the outer packaging as much as possible.On November , the market price of Cangzhou copper bar was stable. According to the monitoring data of Lange Iron and Steel s cloud business platform, the market price of * mm cold drawn steel produced in Linyi is yuan, the market price of * mm in Linyi is yuan, the market price of * mm in Jianlong is yuan, the market price of * mm in Yuanhua is yuan, the market price of * mm in Juneng is yuan, and the market price of * mm in Juneng thermal expansion is yuan.Oldenburg,When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.In consideration of the above factors, more and more steel plants have stopped production since October, and the production limit in Wu an and Tangshan heating seasons has been advanced. In addition, the formal implementation of production limit in & quot; +& quot; urban heating seasons after November by steel enterprises, the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high, and the willingness to further replenish the inventory is not strong. In terms of supply, the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection, the short-term iron ore market may lack upward momentum.Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand, the continuous decline of iron ore port inventory may end. In addition, according to the new statistics of * *, the available days of imported iron ore of steel mills are days, which is one day lower than that before the National Day, and is on the high side of history. The steel mill said that at present, the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction, the steel mill is not willing to replenish the inventory.
